in the c client api:
Is it normal for zoo_state() to return zero (not one of the valid state
consts) when it is handling socket errors?
In the C Code, handle_error(), which handles socket errors, sets the
zh->state to zero,
zh->state = 0;
If the handle is recoverable, why is the state set to zero, which is not
even a valid state const?
Here's a use case where the state should be connecting, but instead is
1) c client connects to a zkserver
2) shutdown zkserver
3) zoo_state() returns zero on a valid zookeeper handle.
We are using zoo_state() to get the state of the connection, and this is
a surprising returned value from this function.
